A slender cylinder in this discussion implies that its diameter is small relative to the wave cylinder diameter, D, shouldbe muchless thanthe wave length, ¸; the methods to be discussed here are oftenusable as long as D ¸.
The impact of a breaking wave on a vertical cylinder is shown in Figure 3. The impact starts at one point in the front line of the cylinder and spreads out radially and tangentially to the surface of the cylinder. Thus, the impact takes place almost simultaneously along the height of the cylinder.

The diameter of the cylinder is mi. Explanation: The centripetal acceleration of the cylinder is given by, a c = r ω 2. r is the radius of the cylinder; ω is the angular speed of the cylinder; The angular speed of the cylinder will be, ω = a c r.
In terms of the diameter of the cylinder, the angular speed will be, ω = 2 a c d. Plane-wave scattering by a perfectly conducting circular cylinder in an isotropic and homogeneous medium is a classical problem, whose solution can be found in sev-eral books of fundamental electromagnetism.1,2 More-over, the case of an arbitrary-cross-section cylinder has been treated by numerical methods.3–7.
